Sienna Miller is interested in appearing in a TV show but finds the thought "daunting".
The actress has appeared in numerous high-profile films such as Alfie, Layer Cake and Factory Girl.
She made the transition to the small screen in British TV movie The Girl, but Sienna has her eye on something like Mad Men or Downton Abbey.
"I would be open to it if it was the right thing. I'd love to do a period drama," she explained to British magazine OK!
"The idea of playing the same character for seven years is really daunting, though, but at the same time, I believe what they're making on television is pretty much superior to most things being made in film nowadays."
Sienna is currently working on comedy romance A Case of You with Evan Rachel Wood and Vince Vaughn.
She has 11-month-old daughter Marlowe with her fiancé Tom Sturridge and says having a child makes her line of work easier.
"It's a strange existence and it can be lonely when you find yourself in another city, in another hotel room, with another group of people," she admitted.
"I'm lucky that I have a baby now, so wherever I go, she'll be with me."
Sienna picks her scripts by feeling and knows she has a good one on her hands when she reads it out loud.
The star has always dreamt of being an actress.
"I was pretty certain from a very young age that this was what I wanted to do," she smiled.
"My first job was not anything to write home about, but I was in a film and I felt like that was the moment."
